What is the percentage of centella in this, please? Other ingredients?

The ingredients are listed on their site:Aqua (Water), Glyceryl Stearate, Hydrogenated Polydecene, Vitis Vinifera (Grape) Seed Oil, Propylene Glycol, Stearic Acid, Palmitic Acid, Squalane, Hydrogenated Vegetable Oil, Persea Gratissima (Avocado) Oil, Algin, Centella Asiatica Leaf Extract, Glycine Soja (Soybean) Oil, Triethanolamine, Allantoin, Cetyl Palmitate, Ethylhexylglycerin, Caprylyl Glycol, Tocopheryl Acetate, Disodium EDTA, Retinyl Palmitate, Phenethyl Alcohol, Tocopherol, Parfum (Fragrance)http://www.cytolnat.com/en/product,content/cytolnat-centella.htmlUnfortunately, they do not list the percentage of Madecassic or Asiaticosides, only the amount per volume of extract, which lists as: *The extract contains a blend of active ingredients from the triterpenic saponosides family, 60% of which is Madecassic and Asiatic acid and 40% is asiaticoside.I will say this product is nice. But not as nice as Madecassol.
